为了给玉米生产中施用微生物菌肥提供依据，在榆中县石头沟和甘州区平原堡研究了禾神元微生物菌肥水剂和颗粒剂对玉米生育期、生物性状、经济性状和产量的影响。结果表明，施用禾神元微生物菌肥后玉米的株高、穗长、穗粗、茎粗、穗位高均较常规施肥有所增加，产量较常规施肥增加5.24%、6.40%，且喷施禾神元微生物菌肥水剂较撒施禾神元微生物菌肥颗粒剂增产0.63%、1.79%，对玉米的生长发育和产量提升效果最好。

In order to provide basis for the application of microbial fertilizer in maize production， The effects of heshenyuan multi-effect microbial fertilizer on maize growth period， biological characters， economic characters and production was studied in Shitougou， Yuzhong County and Pingyuanbao Ganzhou district. The results showed that the plant height， ear length， ear diameter， stem diameter and ear height of maize after water agent and granula application of heshenyuan microbial fertilizer were increased compared with conventional fertilization， and the yield increased by 5.24% and 6.40% compared with conventional fertilization. In comparation with the conventional fertilization， using spray and spread the yield increased by 0.63% and 1.79%， respectively， so the spray treatment had the best effect on maize growth and yield improvement.
